Hello Prudence,

You were close with the nth-child. The correct way would have been.

img:nth-child(4), img:nth-child(3) { clear:both; }

This of course will only apply the clear before the 3rd and 4th child.

@media (min-width: 607px) {
  img{
   float:left; 
  }

   img:nth-child(3n+4){
      clear: left;
   }

}

3n+4 = 4 Is where we start, at the fourth element in this case;

Maybe you'll understand this easier this way:

  • 3*0+4 => 4 nth element is going to be styled
  • 3*1+4 => 7 nth element is going to be styled
  • 3*2+4 => 10 nth element is going to be styled

and so on...
